Novel trithioanhydride complexes of transition metals; X-ray crystallographic characterization of [(η-C5H5)(CO)FeSC(Fp)SCS(Fp)]SO3CF3, [Fp = Fe(CO)2(η-C5H5)]

Abstract

Nucleophilic addition of the thione sulphur atom in the complexes [FpC(S)SML_n][ML_n= Fp or Re(CO)₅; Fp = Fe(CO)₂(η-C₅H₅)] at the thiocarbonyl carbon atom in the complexes [FpCS]₊ gives five-membered metallacycles [(η-C₅H₅)(CO)F[graphic omitted]S(ML_n)]SO₃CF₃, ascertained by an X-ray crystal-structure determination of complex with ML_n= Fp; the reactivity of the exocyclic sulphur atom has been studied.
